Species Profile
Species profile data sourced from the IUCN Red List of Threatened Species.
Marsh Labrador tea faces severe threats from wetland habitat destruction and degradation due to agricultural conversion, urban development, and drainage projects. Climate change is altering precipitation patterns and temperature regimes in its specialized bog and wetland habitats, while pollution from agricultural runoff and industrial activities degrades water quality in these sensitive ecosystems.
Key Facts
Habitat & Distribution
Occupies acidic bogs, peat wetlands, marshy areas, and wet heathlands in northern temperate and subarctic regions. Typically found in nutrient-poor, waterlogged soils with sphagnum moss in elevations ranging from sea level to montane zones.
